MRAG Asia Pacific were engaged by The Nature Conservancy (TNC) to make a preliminary judgement on feasibility of product segregation within Indonesian snapper fisheries operating under a comprehensive Fishery Improvement Program (FIP). The fisheries encompass around 300 fishing vessels, from < 5 GT to 100 GT, operating across 11 Fisheries Management Areas (WPPs). The fishing methods include long-line, drop-line, trap and gill net. Most of the vessels use single gear, with some using mixed gear, targeting 25 species including snapper, grouper, emperors and grunter. Catches transfer through a number of entities following initial harvest and are landed at various collection centres operating within each management zone. The product is then sold through vessel agents to a number of individual processing firms. The fish are filleted, vacuum packed, and labelled according to species, weight, vessel details, and place of capture. These firms sell product to US, Australian, European, and domestic markets. The project involved site visits to key landing sites, fishing villages and processing facilities, as well as review of existing systems and processes for traceability within the supply chain. Recommendations on practical steps to support the development of robust chain of custody arrangement were made.
